Astronomers have discovered the first binary-binary solar system. The discovery is said to have implications on the way people perceive the solar system was formed.

The discovered solar system has two stars as well and a planet revolving. The new binary system has been named HD 87646. It is made up of one star, a brown dwarf star, and a massive planet, according to Science Daily. The large planet is 12 times the mass of Jupiter while the brown dwarf is 57 times the mass of Jupiter. The two are in close proximity as well to the primary star.

What makes the system interesting is that it defies what people know how a solar system is. Typically astronomers think that the solar system formed out of a disk dust cloud, with the large outer planets farther out from the primary star. Yet with HD 87646 the objects are far closer than how the outer planets are in our solar system.

HD 87646 is a binary star system, but the two stars are in close proximity to each other. The larger star is 12 percent more massive than the Sun, while the second is around 10 percent less massive than the Sun, as Phys Org reports. The distance between the two stars is only 22 astronomical units away. That is equivalent to the distance between the Sun and Uranus.

It has been observed that such a distance in astronomical terms is quite close to a binary star system. This becomes even more complex when a planet is orbiting the primary star as well. The arrangement of HD 87646 then defines what people know a solar system to be since the two stars are too close to each other and with a planet revolving around it as well.

The discovery has been made by University of Florida Professor Jian Ge along with Bo Ma. The star system was first surveyed in 2006 during the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS). It was discovered with the help of the Doppler instrument W.M. Keck Exoplanet Tracker, or KeckET. The large planet has been named MARVELS-7a while the brown dwarf is called MARVELS-7b.
